Private equity firm American Securities has acquired Frontier Spinning Mills Holding, one of the largest US based producers of cotton and cotton/polyester blend yarns for the knitting and weaving industries.

American Securities acquired the company from an affiliate of another private equity firm, Sun Capital Partners. Financial terms of the deal were not disclosed.

Yarn produced by Frontier is used in sportswear, undergarments, socks, sweaters, fleece and denim. 

The company is headquartered in Sanford, North Carolina and operates five spinning facilities in North Carolina and Alabama with 1,076 employees.

"We are excited about our new partnership with American Securities, which will further our ability to service our customers worldwide," said Frontier CEO John Bakane.

Kevin Penn, managing director at American Securities, added: "Frontier has long-term relationships with blue chip clients that, when combined with strong, long-term demand for its products, make it an attractive investment for us.

"We look forward to working with the Company's highly talented management team to expand Frontier's capabilities to better serve its growing customer base."
